Even before the 2026 calendar year has begun, the first controversy under F1's new ruleset has already surfaced. It concerns the engine regulations, and more specifically the compression ratio of the ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

After weeks of speculation, the next step in the ongoing power unit compression ratio saga has been decided. On Wednesday, the FIA confirmed details of a new compression ratio measurement technique ...

Formula One will undergo one of the biggest overhauls in its 75-year history in 2026. Arguably its biggest ever. Never before has there been such a fundamental redesign of both power units and chassis ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

A political firestorm has been brewing in Formula 1 in recent weeks and months over whether engine manufacturers have found a loophole in the new 2026 technical regulations. Mercedes and Red Bull may ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel ...

There’s still another couple of months before the 2026 crop of F1 cars takes to the track for the first preseason test. It’s a year of big change for the sport, which is adopting new power unit rules ...

It's as crazy as it sounds. Rolls Royce developed a diesel rotary engine for military applications. Because diesel engines require high compression ratios for compression ignition to occur, they used ...

With every passing day the Mule provides opportunities beyond our original expectations. Since the 467ci engine belongs to HPP editor Tom DeMauro, it is at our beck and call. This affords HPP the ...

You might already know that gasoline and diesel engines both operate using the same four-stroke cycle: intake, compression, power, and exhaust. However, a key difference between gas and diesel engines ...
